The diff adds the mandatory `retoor <retoor@molodetz.nl>` header comment to every `.py` file under `devplacepy/` (including `__init__.py` and `routers/__init__.py`), and updates the `StyleAgent` in `agents/style.py` to instruct agents to only add the header on created or already-edited files rather than sweeping the entire repo. The `agents/base.py` operating protocol is also revised to reorder and clarify tool discipline rules.
Introduce a new `/leaderboard` endpoint ranking top 50 members by total stars, wire it into the app router and documentation. Implement `_backfill_gamification()` in `database.py` to compute XP/levels for existing accounts from prior posts, comments, votes, and follows. Extract `is_owner()`, `create_content_item()`, and `detail_context()` into `content.py` to centralize content creation, reward awarding, mention notifications, and attachment linking. Update comment creation/deletion in `comments.py` to use `award_rewards()` with `XP_COMMENT` and the new `is_owner()` helper. Add shared template partials documentation for vote bars, star buttons, post headers, and topic selectors to `AGENTS.md`.
Replace static form-based vote buttons with a new VoteManager class that submits votes via fetch, returns JSON with net/up/down/current value, and updates vote count spans using data-vote-count attributes across all templates. Add JSONResponse endpoint in votes router for AJAX requests, switch VoteManager import from Http to Toast for error feedback, and refactor link_attachments to handle comma-separated UIDs.
Extract duplicate target-redirect logic from comments router into a new `resolve_object_url` database function, add `target_url` field to follow and message notifications, create `/notifications/open/{uid}` endpoint that marks notifications read and redirects to their target, implement client-side NotificationManager for card clicks and comment hash scrolling, and add comment-highlight CSS animation.
Introduce `update_target_stars`, `get_target_owner_uid`, and `VOTABLE_TARGETS`/`STAR_TARGETS` in database.py; replace inline badge insertion with `award_badge()` and inline notification creation with `create_notification()` across auth, comments, and follow routers; add `enrich_items()` in new content module to centralize post/gist list assembly and remove duplicated enrichment logic from feed and gists routers.
